EDIT: For some context, I recently gave podman another go. I have a few services on my homelab server set up in docker containers, so I tried migrating to podman.

After the second major bug (open issue on github) I encountered looked like it would require completely dropping using compose files to work around, I gave up and went back to docker.

I like the idea of podman, but it’s just not stable. I’ll try again in a year or so.

As a bonus, docker’s CLI is significantly nicer.

I agree that ergonomics are also important, but for me not the top priority for me. For Podman, I like the way I can use Quadlet to quickly deploy and run containerized stuff.

However I really like it for building and running my own app stack pods. The combination of Quadlet and SystemD instance aliases is very powerful. I use this to drive all kinds of configuration automation.

    all kinds of configuration automation.

    Any cool examples? I'm still dipping my toes into systemd

    The usage is simple. If you name a quadlet (or systemd service unit file) with an @ in it then you can use it. Like foo@.container then anything you put between the @ and . is passed into the resulting unit file as %i.

    So systemctl start foo@bar.service will pass 'bar' in where %i exists in the unit file. From there you can use it in a StartPreExec or whatever else to do instance specific stuff when the instance of the containerized service start.

    Like ExecStartPre=/usr/local/bin/activate_config %i for example. A contrived example but hopefully you get the idea: with one quadlet file and a little scripting you can start many instances of a service that each automatically pull in their own configs.
